Qualcomm is the most popular manufacturer of chipsets for mobile devices. Therefore, everyone was scarified by information about the latest exploits call QuadRooter. The only thing which have to do the attacker is to convince you to install a malicious app which uses one of the four flaws. These security vulnerabilities are present in any Qualcomm Snapdragon powered Android smartphone.
This security risk was discovered by Check Point company and they have confirmed that even BlackBerry DTEK50 (BackBerry claims that this is the safest smartphone on the market) mobile is affected. Also, other popular high-end smartphones, like Nexus 5X, Nexus 6, Nexus 6P, HTC One M9, HTC 10, Samsung Galaxy S7 and Samsung Galaxy S7 edge, can be attacked in the same way.
Fortunately, Google’s ‘Verify Apps’ feature protects us from QuadRooter exploits.
This is very good news, because Verify Apps feature was introduced in Android 4.2 and it is enabled by default. Therefore, 90% of the Android smartphones are protected. Of course, the Qualcomm will prepare the fix which will be included in the monthly security update which Google sends to Nexus mobiles and also other vendors in their own updates. To be honest, this is good to know that Android has already some security mechanisms which can detect malicious applications. A lot of people have smartphones which are not maintained by manufacturers and they will not receive any update. In case of Stagefright I had to disable MMS service on all my old Android smartphones.
